Re: How many miles before clutch pads needs replacing
I think it has a lot to do with how you use the clutch.
I have never had a single clutch issue in my chinagirl career, but I have seen some customer bikes with worn out pads. It's almost always the new riders or the hot rods who have clutch problems.
The older guys with lots of miles just don't wear them out. I've seen over 10k on one HT clutch with a 230lb rider, a tuned pipe, and a 36tooth sprocket with no pad wear problems.
Just my opinion
If more is better, then too much is just enough.
If you can't afford it, build it yourself.
